Sahih Muslim Book - 6, Hadith - 1671

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدِ بْنِ أَسْمَاءَ الضُّبَعِىُّ حَدَّثَنَا مَهْدِىٌّ - وَهُوَ ابْنُ مَيْمُونٍ - حَدَّثَنَا وَاصِلٌ مَوْلَى أَبِى عُيَيْنَةَ عَنْ يَحْيَى بْنِ عُقَيْلٍ عَنْ يَحْيَى بْنِ يَعْمَرَ عَنْ أَبِى الأَسْوَدِ الدُّؤَلِىِّ عَنْ أَبِى ذَرٍّ عَنِ النَّبِىِّ -صلى الله عليه وسلم- أَنَّهُ قَالَ « يُصْبِحُ عَلَى كُلِّ سُلاَمَى مِنْ أَحَدِكُمْ صَدَقَةٌ فَكُلُّ تَسْبِيحَةٍ صَدَقَةٌ وَكُلُّ تَحْمِيدَةٍ صَدَقَةٌ وَكُلُّ تَهْلِيلَةٍ صَدَقَةٌ وَكُلُّ تَكْبِيرَةٍ صَدَقَةٌ وَأَمْرٌ بِالْمَعْرُوفِ صَدَقَةٌ وَنَهْىٌ عَنِ الْمُنْكَرِ صَدَقَةٌ وَيُجْزِئُ مِنْ ذَلِكَ رَكْعَتَانِ يَرْكَعُهُمَا مِنَ الضُّحَى ».

It was narrated from Abu Dharr that the Prophet (s.a.w) said: "In the morning a charity is due from every joint of one of you. Every Tasbihah is a charity, every Tahmidah is a charity, every Tahlilah is a charity, every Takbirah is a charity, enjoining what is good is a charity, forbidding what is evil is a charity, and two Rak'ah offered in the forenoon (Duha) will suffice for that."
